Multiphase Science and Technology (MST) publishes novel research work covering all aspects of multiphase systems. The scope of MST encompasses theoretical concepts, physical modeling, experimental techniques, and numerical simulations. Main research areas include but are not limited to mechanics of interfaces, internal flows, external flows, multiphase flow modeling, measuring techniques, micro-and nano-fluidics, and multiphase bio-systems.MST accepts the following manuscripts for publication: Short communications, which should not exceed 4 pages starting with a brief abstract. These communications should not contain section headings and should be accompanied by a statement of justification for the reason for rapid publication in the form of a covering letter to the Editor. Full-length papers of original, high-quality research:The format of the full papers should start with a brief abstract followed by an introduction section; followed by sections containing results and discussion, conclusions, references, and appendices if necessary. Highlights and Reviews: "Highlight" papers give authors the opportunity to highlight the importance of a new topic of particular interest to the community by discussing its importance, challenges that it faces, and identify future research opportunities. Authors could also use this opportunity to highlight growing/emerging areas in multiphase science. These papers should not contain new research and should not exceed 6 pages in MST format; these articles are normally published via invitation by the Editorial Board. Review papers are normally published via invitation by the Editorial Board and should correspond to critical reviews and/or tutorial papers on a broad subject. Position Papers: These are papers on 'hot' research themes of topical interest. These papers may be invited by the Editorial Board or unsolicited, have a similar format to that of the Letter/Brief communications (see above) and should not exceed 4 pages in length. The author(s) of these papers have an opportunity to communicate their personal opinion (which could be speculative and controversial) on a particular topic, and/or comment on a recent paper in MST; in the latter case, the authors of the relevant paper will be given the opportunity to respond to these comments in the same issue. Special Issues: There may be scope to dedicate an entire issue to the publication of several, full-length papers on a given topic of particular interest to the community. The publication of these issues follows a detailed statement of justification for the dedication of an entire MST issue for one topic. Photo and Video Gallery: A gallery photos and videos of multiphase flow experiments or simulations, selected from research published in MST, will be published on the MST website once a year.

The motion of a gas-liquid interface along a solid wall is influenced by the capillary forces resulting from the interface's shape and its interaction with the solid, where it forms a dynamic contact angle. Capillary models play a significant role in the management of cryogenic propellants in space, where surface tension dominates the behavior of gas-liquid interfaces. Yet most empirical models have been derived in configurations dominated by viscous forces. In this study, we experimentally investigate the wetting of a low-viscosity, highly wetting fluid in a reduced gravity environment. Our setup consisted of a transparent and diverging U-tube in which capillary forces sustain the liquid motion. Combining particle image velocimetry (PIV) and high-speed backlighting visualization, the experimental campaign allowed for measuring the interface evolution and the velocity field within the liquid under varying gravity levels. This work reports on the preliminary results from the image velocimetry and shows that the velocity profile within the tube is close to parabolic until a short distance from the interface. Nevertheless, classic 1-D models for capillary rise face difficulties reproducing the interface dynamics, suggesting that the treatment of the surface tension in these problems must be reviewed.

“…Very few experimental data exist because of the complexity to maintain microgravity conditions for a long period of time. Parabolic flights and drop towers enable to create several seconds of microgravity environment (Fernandez et al 2017;Li et al 2018) but low Bond numbers manoeuvres require several minutes for the fluids to stabilise. Finally, Direct Numerical Simulation is a promising candidate to investigate the fluids behaviour during station-keeping manoeuvres.…”
